Cautions on Safety
(Make sure to read this paragraph before using the unit.)
Thoroughly read this manual, a separate USER'S MANUAL and all attached documents of the connected
programmable controller (hereafter referred to as "PLC") and other related units before starting installation,
operation and inspection/maintenance of the temperature control block. Acquire the knowledge on
equipment, the information on safety and all cautions before using the temperature control block.
In this instruction manual, cautions on safety are classified as "DANGER" or "CAUTION".
This symbol indicates that incorrect handling may generate a dangerous situation which may lead
to death or serious injury.
This symbol indicates that incorrect handling may generate a dangerous situation which may lead
to medium or minor injury or physical damage.
Even an item classified as "CAUTION" may lead to a severe result depending on the situation.
Each item describes important information. Make sure to observe each item marked with "DANGER" or
"CAUTION".
Carefully store the instruction manual offered together with the temperature control block so that the
operator can refer to it at any time necessary. Make sure to deliver the instruction manual to the end user.
We appreciate it very much that you have purchased the temperature control block FX
programmable controller.
This manual describes handling of the MELSEC-F Series Temperature Control Block FX
Thoroughly read this manual and other manuals of related products, and sufficiently understand the
specifications before use.
Make sure to deliver this manual to the end user.

1. Outline of Product
Cautions on design
•
Install a safety circuit outside the PLC so that the entire system conservatively operates even if
an abnormality occurs in the external power supply or a failure occurs in the PLC.
If the safety circuit is installed inside the PLC, malfunction and erroneous output may cause
USER'S GUIDE
accidents.
Make sure to construct an emergency stop circuit, protection circuit, interlock circuit to prevent
damage to a machine or instrument outside the PLC.
JY992D85601C
•
When the PLC or FX
value error by the self-diagnosis circuit, and all outputs turn off. When an abnormality occurs in
the I/O control area which cannot be detected by the CPU in the PLC, output control may be
disabled.
Design external circuits and the structure so that the entire system conservatively operates in
such cases.
•
When a failure occurs in a relay, transistor, triac, etc. in the FX
outputs may keep ON or OFF.
For output signals which may lead to severe accidents, design external circuits and the struc-
ture so that the entire system conservatively operates.
Caution on disposal
•
When disposing of the unit, treat it as industrial waste.
The temperature control block FX
equipped with two temperature input points and two transistor (open collector) output points is a special
block to control outputs of temperature inputs from thermocouples and platinum resistance thermometer
bulbs by PID control.

Cautions on installation
•
Use the unit in the environment for the general specifications described in the manual.
Never use the unit in a place with dust, soot, conductive dust, corrosive gas or flammable gas,
a place exposed to high temperature, dew condensation or rain and wind or a place exposed
to vibration or impact.
If the unit is used in such a place, electrical shock, fire, malfunction, damage in the product or
deterioration of the product may be caused.
•
Never drop cutting chips or electric wire chips into the ventilation window of the FX
while drilling screw holes or wiring cables.
Such chips may cause fire, failure or malfunction.
•
After finishing installation, remove a dust preventing sheet adhered on the ventilation window
of the PLC and the FX
If the sheet remains attached, fire, failure or malfunction may be caused.
•
Securely connect connection cables such as extension cables and memory cassettes to specified
connectors.
Imperfect contact may cause malfunction.
The FX
-2LC can be installed on the right side of an FX
2N
extension unit.
The FX
-2LC can be attached with a DIN rail DIN46277 (width: 35 mm) or directly attached to a panel
2N
surface with screws (M4).

Assure the interval of 1 to 2 mm between a unit or block installed on the left side of the FX
4. Connection to PLC Main Unit
Connect the FX
-2LC to the PLC main unit with an extension cable.
2N
Terminal block
FX
-2LC units are treated as special units of the PLC, and the special unit No. 0 to 7 is automatically
2N
assigned to each FX
-2LC unit from the one nearest to the PLC main unit. (These unit Nos. are used in
2N
FROM/TO instructions.)
One FX
-2LC unit occupies eight I/O points in the PLC main unit.
